Parr Instrument Company

Parr Instrument Company was founded in 1899 in Champaign, Illinois as the Standard Calorimeter Company by S.W. Manufacturing operations of the Standard Calorimeter Company were moved to East Moline, Illinois in 1911. During World War II the company manufactured high precision machine parts under contract with suppliers to the war effort, while continuing to produce calorimeters and other laboratory apparatus to the extent permitted by the limited availability of critical raw materials. Having devoted its attention specifically to these specialty products for over one hundred years, the Parr Instrument Company has developed a fine reputation among chemists and scientists throughout the world as a dependable supplier of top quality laboratory equipment. Since its founding in 1899, Parr Instrument Company has been engaged exclusively in the manufacture and sale of chemical reactors, pressure vessels, calorimeters, combustion vessels, and related equipment developed specifically for laboratory use. Throughout its long history the primary emphasis in all Parr manufacturing has been to provide its customers with quality apparatus, carefully designed for each application and backed by a competent technical support staff with many years of experience in this specialized field.
